Requests for the song’s release have been flooding in since it was first used in the drama’s opening credits, and also when it was used in many of the drama’s most important scenes. The original track was 50 seconds long and sung by Han Soo Ji, and it has been fleshed out to a 3 minute 30 second-long song through a collaboration with Heize.

The intro begins with Han Soo Ji’s mystical voice, and Heize layers their voices with a vocal technique she hasn’t used before. The song’s lyrics fit perfectly with the overall theme of “Goblin,” speaking of past lives, reincarnations, and fateful love.

Ailee’s “I Will Go to You Like the First Snow” is still in first place on the Melon charts, and is also doing well on other charts as well.
